GENERAL TERMS AND CONDITIONS

(continued)

5.2 Receipt Nominations and Allocation Methodology. Except as

otherwise provided in this Tariff, Shipper shall furnish receipt

nominations to Transporter for all quantities of Gas Shipper

desires Transporter to receive, including applicable Fuel Use and

LUFG retentions. All nominations shall be prospective only, and

must be made electronically except during emergency events as

provided in Section 22.8 of these General Terms and Conditions.

Transporter may rely on such receipt nominations for all purposes

and shall not be responsible or liable for disputes arising from

such nominations or actions taken in accordance with this section.

At a physical Receipt Point, unless there is an operational

balancing agreement in effect, one of the standard allocation

methodologies, inter alia, will be determined in accordance with

NAESB Standards after or during confirmation and prior to gas

flow. Pursuant to NAESB Standard 2.3.16, the list of allocation

methodology types is as follows:

A. ranked;

B. pro rata;

C. percentage;

D. swing; and

E. Operator provided value.

The types of allocation methodologies is a list from which two

parties may agree. If the two parties cannot agree upon an

allocation methodology, pro rata based upon confirmed (and

scheduled) nominations is the default method, and the primary

measuring party will provide the allocation using such

methodology. Only one pre-determined allocation methodology

should be applied per allocation period. Transporter and Operator

may memorialize their pre-determined allocation methodology

agreement by entering into a Predetermined Allocation Agreement in

the form beginning on Sheet No. 783 of this Tariff, provided that

such Operator is pre-qualified for creditworthiness purposes

pursuant to Section 14.5 below.
